Definitions
- the present invention relates to a method for producing solutions with Acid groups of functionalized polymers through the use of Microwave radiation, a process for the production of solid, soluble and insoluble polymers, as well as the use of the solutions.
- the derivatives of these polymers which are functionalized with acid groups such as, for example, -SO 3 H, -B (OH) 2 , -CO 2 H and -PO 3 H are, depending on their degree of functionalization, soluble in solvents such as dimethylformamide, dimethyl sulfoxide, dimethylacetamide or N- Methyl pyrrolidone. With particularly high degrees of functionalization, these polymers can also become water-soluble.
- US 5 453 161 discloses the preparation of polyimides which are derived from 3,3 ', 4,4'-benzophenonetetracarboxylic acid derive, the reaction mixture with Microwave radiation is heated. The product will not become water-soluble reported.
- JP-05 310 907 discloses a method for removing methylene chloride from Polymers by using microwave radiation.
- One versus classical methods of heat input according to increased solubility of the polymers microwave radiation is not reported.
- the task was a Process to develop using polymers that carry acid groups in one mold can be prepared that have a more easy solubility in water and organic solvents.
- the invention relates to a process for the preparation of aqueous, aqueous and non-aqueous solutions of with acid groups Functionalized polymers, characterized in that the for the production of Solution necessary heat is supplied by microwave radiation.
- the main solvents used are water, dimethylacetamide, N-methylpyrrolidone, dimethylformamide, dimethyl sulfoxide, alcohols such as. B. Isopropanol and mixtures of two or more of these substances in question.
- Polyether ketones, polyphenylene sulfides, partially or perfluorinated aliphatic polymers or polyether sulfones are preferably used as polymers, in particular those with an ion exchange capacity (IEC) of between 0.5 and 2 mmol acid function per g polymer.
- IEC ion exchange capacity
- the use of polymers of the formula 1 is particularly preferred which are marketed by DuPont under the trade name ®Nafion.
- Another object of the invention is a method for obtaining the solid Polymers from the microwave irradiated solutions. These polymers are after Carrying out the process according to the invention insoluble in the solvent, from which they were obtained.
- the solutions of the polymers for example in water, can be evaporated to dryness become.
- the solid polymer thus recovered can be found in e.g. Water by heating Bring in solution without microwave radiation, or by tempem into one bring water-insoluble state from which it in turn passes through Microwave radiation into a soluble, e.g. water-soluble state can be transferred.
- This surprising property has the advantage that the polymers are in one Let soluble form be transported without solvent, then without Microwave radiation can be solved and after processing and the Evaporate the solvent by annealing to an insoluble state can be transferred.
- solutions prepared by the process according to the invention are suitable for example for the production of gas diffusion electrodes, fuel cells and polymer electrolyte stabilized platinum nanoparticles.
- a microwave oven was used in all attempts to solve the problem with microwave radiation made by CET, model MDS 2000.
- the device is used for security reasons only with 50% of the nominal output, a pressure limitation of 3.99 bar and one Operating temperature limit of 175 ° C.
- sample vessels were screwable Teflon autoclaves used. The sample vessels are in front Switching on the microwave radiation flushed with nitrogen.
- Example 1 Sulfonated PEEK, dissolving in water with microwave radiation
- Example 2 Sulfonated PEEKK, dissolving in water under microwave radiation
- Example 4 Sulfonated PEEK, dissolving in N-methylpyrrolidone with Microwave radiation
